Frequently Asked Questions

Q What is the primary function of OFL7 Series Miniature Circuit Breakers (MCBs)?

The OFL7 Series MCBs are designed to automatically switch off electrical circuits during abnormal conditions such as overloads and short circuits, protecting connected electrical devices and wiring from damage.

Q What is the difference between 2P, 3P, and 4P Miniature Circuit Breakers?

The number of poles indicates the number of separate electrical lines the MCB can control and protect simultaneously: 2P is typically used for single-phase systems (live and neutral), 3P for three-phase systems without neutral, and 4P for three-phase systems including the neutral line.

Q How do I choose the correct pole configuration for my installation?

Select 2P for standard single-phase 220V/240V equipment, 3P for standard 380V/415V three-phase motors or industrial equipment, and 4P when full neutral line isolation is required for three-phase electrical distribution systems.

Q Can OFL7 Series MCBs be installed in standard electrical distribution boards?

Yes, OFL7 Series MCBs feature standardized DIN-rail mounting specifications, making them compatible with most standard residential, commercial, and industrial distribution enclosures.

Q What safety features are integrated into the OFL7 Series design?

The series features flame-retardant housing materials, high breaking capacity mechanisms, clear position indicators, and fast-response thermal-magnetic tripping mechanisms for optimum protection.
